Buderus Sensor 7099164

The Buderus 7099164 is a sensor supplied as a thermistor for Buderus gas boilers. It is listed within the gas boiler spares range and is used to monitor temperature at its designated point in the appliance, feeding that signal back to the boiler control. It is the sensor referenced by Buderus part number 7099164.

• Boiler locks out or interrupts the heating or hot water cycle with a temperature-related fault code.
• Flow or return temperature readings that are implausible, erratic or clearly inconsistent with the system.
• The boiler runs on a short cycle, firing and shutting down more often than expected.
• Hot water temperature that fluctuates or fails to reach the set point.
• Visible damage to the sensor body, wiring or connector.

• Confirm the appliance model is Buderus 600-28C before ordering.
• Check the existing sensor and its connector against the part, as wiring and fitment differ between sensor positions.
• Verify the fault is temperature-sensing related rather than a control or circulation issue before replacing the part.
• Note the Buderus part number 7099164 when checking against any documentation for the appliance.
